If i get one I am going with corsa for sure. They are a little expensive, but you get what you pay for. I looked on youtube at different exhausts on corvettes, mustangs and challengers and corsa always sounded the loudest and meanest and had no drone.

The Hooker Maxflow made the best power while still being very quiet at idle/2000rpm, but nice and loud at WOT. The Bassani Real Street also made nice power without being too loud.

FYI flowmasts I would agree sound pretty nice, but they don't do much for power, and exhaust systems with a better compromise of the 2 exist.

What about GMMG chambered exhaust, I know they will be doing something for the 5th gen Camaro right??

Yeah the GMPP is offering actually 3 exhaust. 2 for both the ls3/l99 and one for the ls3 in the v8's.

Do you mean GMMG, and if so where did you hear about that and where can I find more info? If GMMG comes out with a chambered system I know where I'm going!!

All of them are listed in the GM performance catalog someone linked in a post in this section. Its on page 324 i think...no prices just the parts and the part numbers.

Loudmouth (LM) on a Camaro/Firebird? If so, I have and its pretty cool, unless you hate rasp and drone... LOL! With LTs and no cats', you're asking to go deaf. The rasp is really bad. If you get the LM II it's a lot better. I like what they just changed on their F-body design. GMHTP just tested their new LTs for 4th Gens. and the LM and got good numbers, although I don't recall them. I don't think a person would get much more power over your DD as long as that restrictor was cut out of it for max' flow.

I'm sorry if I ranted for nothing if that's not what you meant, LOL!

Does anyone know who is making the GMPP exhausts? Just asking because the Cobalt cat-backs from GMPP are actually made by Borla. (and sound great)

i have a question. i have only had one aftermarket exhaust system and that was flowmaster cat back. im confused after reading on here about the exhaust systems. so if you change your exhaust system does that also change your cats or should you change them as well? sorry if this is a dumb question

If you buy a cat-back system it bolts up behind the cats and are a pipe/muffler/tip combo. My previous Camaro/Corvette had an H pipe from the factory between the manifolds and the mufflers. This is the part of the system that has the cats installed into it. If you were going to get a full system it would include equal length headers (to replace the usually crappy flowing cast iron manifolds that come stock) and an X pipe to replace the stock H pipe which will also help for a more direct flow. These can either come as offroad (no cats) or with high flow cats if you have to deal with emissions standards in your state.

There were 2 cats on my camaro and vette. I've heard of older Mustangs having as many as 6 or 7 cats, lol. I got an X pipe with no cats (saved about 400 bucks and there are no emissions laws where I live anyway) on both my cars so I had to get "dummy" O2 sensors installed on my Camaro and the Vette we just reprogrammed the computer to keep it from triggering error codes about the O2 levels.

If you are just wanting a different sound then go with the cat-back/GMPP exhaust upgrade kit since the sounds all about the mufflers. If you are wanting more power then that's where the headers and a full 3" system w/ X pipe would come into play. As stated in other treads you will prob see 20-30 more HP to the wheels with just headers. I saw ~22hp to the wheels after adding headers on my LS1 vette. Trust me if you do a full system you will be able to feel the difference in performance the next time you drive your car. Hope this helps

Not if you get a cat back system because they only change what comes after the catalytic converter(s), hence the name "cat back" (from the cats...back). But if you really want to get the most out of your (legal) after market exhaust setup you may want to add some high flow cats or get a complete sytem that already has them.

Exhaust Sound

To hear different systems on the LS3, go to youtube and type in
LS3 exhaust.
There are vet and G8 clips with sound.

flow is flow, sound is sound, but when you are comparing two different motors to figure out what is best, it doesnt work.

same thing as the flowmaster exhaust. they sound great on mustangs, but sound like ass on 3rd and 4th gen f-body's. Magnaflow sounds great on both.

if you just change the cat-back system then all you are changing is the tubing from the catalytic converters back. if you are swapping your exhaust manifolds to headers that is something different as well.

Like I said, the SS makes more power, ie from a power production standpoint, the more inferior flowing muffler designs (which performed poorly in this mustang test), will perform as a percentage, even worse vs the better performing mufflers, on a higher hp/tq car.

The tests ARE applicable, only exacerbated even more, to the good or bad, since the LS3 makes more hp/tq vs the lesser 4.6. The systems are BOTH true dual, x pipe designs, using exhaust manifolds, almost identical in design, save the piping diameter, which probably is only a 1/4" or so smaller on the mustang. Could that affect sound, sure, will it affect power, sure, but the rankings unlikely, the power numbers will just be higher from a higher hp motor.

Plus, trying to re-create a similar comparison would be nearly impossible, and since this is the best anyone has, comparing this many exhausts, I for one am willing to use it...it has be posted and used numberous times on LS1tech.

I had a flowmaster initially on my LT1 car...it was no where in the same league soundwise as a mustang...the exhaust systems though are TOTALLY different in design, true dual (mustang) vs single-in-dual out f-body (with one cat on my 94'), so the expectation would be different sound. Chevy did a great thing going to the true dual set up on the new SS, it will allow superior flow and superior sound...

For my budget the best compromise of sound and power will likely be in the form of a magnaflow exhaust...usually all stainless design, good flowing mufflers and usually not overly loud, and best of all affordable...$0.02

When it comes to exhausts, I think it is very important to know that every car is different, and so is every exhaust. Names are not as important as performance, so we have to remember that any exhaust can produce better numbers than any other based on design. Some people get really attached to that one they had on their last car, but a different company may have done better research and development, leading to a more specialized product for your car. The only way to properly compare exhausts is to find some sort of independent testing and a whole bunch of sound clips. Seek out as many dynos as possible of cars with no other modifications than the part you are investigating.

nice quiet drive by GMMG chambered (w/cats I'm sure. Open chambered exhaust rattles your neighbors windows)

hi speed fly-by sounds gooood.

The tests ARE applicable, only exacerbated even more, to the good or bad, since the LS3 makes more hp/tq vs the lesser 4.6. The systems are BOTH true dual, x pipe designs, using exhaust manifolds, almost identical in design, save the piping diameter, which probably is only a 1/4" or so smaller on the mustang. Could that affect sound, sure, will it affect power, sure, but the rankings unlikely, the power numbers will just be higher from a higher hp motor.

Plus, trying to re-create a similar comparison would be nearly impossible, and since this is the best anyone has, comparing this many exhausts, I for one am willing to use it...it has be posted and used numberous times on LS1tech.

I had a flowmaster initially on my LT1 car...it was no where in the same league soundwise as a mustang...the exhaust systems though are TOTALLY different in design, true dual (mustang) vs single-in-dual out f-body (with one cat on my 94'), so the expectation would be different sound. Chevy did a great thing going to the true dual set up on the new SS, it will allow superior flow and superior sound...

For my budget the best compromise of sound and power will likely be in the form of a magnaflow exhaust...usually all stainless design, good flowing mufflers and usually not overly loud, and best of all affordable...$0.02
but the thing to keep in mind is the fact that while they are both true dual exhausts, different size tubing being used, different baffles/chambers being used all have their part to play. a design that works for the mustang might not work for the Camaro.

in a broad sense, yes you can use that test to compare, but until these companies put something on this car and compare them, its not much use. +


and with the single-in dual-out vs true dual, its hard to fight for flowmaster when every other catback manufacturer's exhaust sounded 10 times better on f-body's with the same single-in dual-out design.

Oh I would agree, "blowmaster" sucks...I have the 3 chamber on my 65 chevy, 355 decent sized cam, with LT headers, 2 1/2" exhaust and H pipe, it sounds killer...like a fox body 5.0 stang, but I personally don't plan on that getting any where near my SS. My wife will be driving it and I have orders, NOT LOUD, so I have to find a compromise of power/quiet. Soon enough, hopefully, we will see our options and be able to make some decisions...its an exciting time, if the economy doesn't ruin it for us.
